The configuration on Device B and Device C is similar to that on Device A. The configuration on Device
D and Device E is also similar to that on Device A except that it is not necessary to enable IGMP on the
corresponding interfaces on these two routers.
Step3 Configure the SSM group range
# Configure the SSM group range to be 232.1.1.0/24 on Device A.
[DeviceA] acl number 2000
[DeviceA-acl-basic-2000] rule permit source 232.1.1.0 0.0.0.255

The configuration on Device B, Device C, Device D and Device E is similar to that on Device A.
Step4 Verify the configuration
Use the display pim interface command to view the PIM configuration and running status on each
interface. For example:
# Verify the PIM configuration information on Device A.
[DeviceA] display pim interface
VPN-Instance: public net

Assume that Host A needs to receive the information a specific multicast source S (10.110.5.100/24)
sends to multicast group G (232.1.1.1). Device A builds an SPT towards the multicast source. The routers
on the SPT path (Device A and Device D) have generated (S, G) entry, while Device E, which is not on the
SPT path, does not have multicast routing entries. You can use the display pim routing-table
command to view the PIM routing table information on each device. For example:
# View the PIM routing table information on Device A.
[DeviceA] display pim routing-table
